IMPROVEMENT lN- DEVICES FOR THROWING BELTS ON PULLEVS.

Specification forming part of Letters Patent No. 189,263, dated April 3,1877; application filed January 4, 1877.

To all whom it may concern Be it known that I, ROBERT REINHARD, ofLangendreer, in the county of Bochum, Prussia, have invented a new andImproved Device for Throwing Belts on Pulleys; and I do hereby declarethat the following is a full, clear, and exact description of the same.

The object of my invention is to provide a simple, cheap, and efficientdevice for applying broad or tightly-stretched bands or belts topulleys, and thereby avoid the difficulty and danger incident to suchoperation when effected by hand, in the usual way.

The accompanying drawing, forming part of this specification, shows theconstruction of said device, and also the manner of applying it inpractice.

Figure 1 is a plan view of the device. Fig. 2 is a side view. Figs. 3and 4 show the manner of applying the device in practice.

The device consists of a slotted plate, A, having a spring-clamp, B, forholding the edge of the belt, a'screw-threaded rod, 0, which is rigidlyattached to said plate, and also placed at right angles to it, and abent or curved arm, D, adapted to slide on the screw-rod O, and to beheld in any adjustment by means of a winged nut, E.

The clamping-bar B is arranged to work in a lengthwise slot of plate A,pivoted thereto at its middle, and provided with springs a, coiledaround its trunnions or journals, for the purpose of causingthe bar topress tightly against the edge of the belt, when inserted between it andthe plate A, as shown in Fig. 3, and thus hold the belt securely. Thedevice is secured to a pulley, F, by placing the plate A with its innerside against the edge of the latter, and the bent arm D against thecontiguous spoke, as shown in Figs. 3 and 4, the plate being, in suchcase, radial to the axis of the pulley. The nut E is then screwed uptightly against the arm D, thus causing the plate to press against theedge of the pulley-rim to the same degree the arm presses against thespoke in the opposite direction.

The edge of the pulley is received into a transverse groove, g, in theplate, and the latter is thereby prevented from being thrown out of itsradial position by the strain of the belt when clamped thereto. Thislast result is efl'ected-by turning the bar on its journal to raise itslower end out of the slot, and placing the belt beneath said lower endof the bar. The action of the coiled springs h then causes the bar toclamp the belt and hold it securely till the rotation of the pulleycarries the device around, and thus throws on the belt, the latter beingsimultaneously freed from the clamp by its own tension.

The belt is thus applied without the difficulty, delay, and personaldanger attending the operation when effected in the usual way.

The device can remain attached to the pulley after the belt has beenthrown on, until such time as convenience may allow its removal.

What I claim is-- The device hereinbefore described, consisting of aplate, A, having a groove, 0, and a spring clamping-bar, B, a screw-rodrigidly attached to part A, at right angles, an arm, D, adapted to slideon the rod, and a nut for securing it in any adjustment, substantiallyas shown and described, to operate as specifled.

The above specification of my invention iggngd by me this 28th day ofNovember, A. l 76.

ROBERT REINHARD.
